The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
With reference to
the first rod 41 is formed in a V shape, and the second rod 42 is straight, two top ends of two sides of the first rod 41 are axially connected with the holding surface 3 individually by using two screws 8, a bottom end of two sides of the first rod 41 is connected with the column 2 by ways of a sliding member 5, a top end of the second rod 42 is axially coupled with the holding surface 3 by ways of one screw 8, and a bottom end of the second rod 42 is fitted onto the column 2;
the column 2 includes a positing strap 6 with a plurality of teeth, and the sliding member 5 is adjusted upward or downward for being further fixed on the positioning strap 6 by using a retainer 7, and the second rod 42 fitted onto the column 2 is adjusted upward or downward for being further fixed on the positioning strap 6 by means of the retainer 7;
each of teeth of the positioning strap 6 is formed by selecting from a triangle, a rectangle, and a trapezium shapes, and one of three acute angles of the tooth faces upward so that the positioning strap 6 is used to position the sliding member 5 and the second rod 42 securely;
the holding surface 3 is curved or flat and made by selecting from soft net, cloth, and feather materials to comfort a user's legs;
a cross section of the column 2 is formed in a triangle shape, the base 1 is formed in a 8 shape, the column 2 and the base 1 are connected together by using one screw 8.
